According to work needs to choose the electromagnetic stainless steel control
1 When the electromagnetic stainless steel requires a long time to open, and the continuous opening time greatly exceeds the closing time, the normally open type should be used. 2 If the opening and closing time is similar, choose the normally closed type. 3 For the conditions of safety protection, such as kiln flame detection, gas leak alarm, fire safety system, should choose emergency cut off electromagnetic stainless steel or a new technology, long-term power, loss of electricity off, manual pull-open electromagnetic stainless steel. 4 Self-retaining electromagnetic stainless steel (also known as bistable) is a new technology, which is mainly used in places where energy saving or ultra-high temperature and low pressure driving is required. Fourth, the power voltage selection: as far as possible the preferred choice of commonly used AC220V, DC24V more convenient, other voltages are also optional. Fifth, choose the principle structure type of electromagnetic stainless steel according to the pressure level 1 Nominal pressure: This parameter has the same meaning as other general valves and refers to 1.5 times the pressure used. 2 working pressure: refers to the electromagnetic stainless steel in the closed state, the valve pressure at the front end of the valve minus the valve back line pressure value; the working pressure in the 0-0.1Mpa or vacuum, the general choice of small diameter DN15 below automatic , Large-diameter DN15 above selected automatic distribution. When the working pressure is not less than 0.1MP, the type of the pilot structure is generally selected. High-voltage electromagnetic stainless steel is generally a pilot structure.
